Specifications include, but are not limited to: HWRP is seeking a qualified consulting firm to provide technical support in performing a study and work plan to evaluate and address compliance of acute toxicity due to ammonia. The scope of services includes, but is not limited to the following: Task 1: Study on Projected Effects of Water Conservation and Planned Recycling on HWRP Effluent Acute Toxicity and Ammonia as Required by the LARWQCB. Special Study Objectives: The objectives of this HWRP special study are: 1. Calculate and evaluate the mass nitrogen loading in the Plant for past, current, and projected flows to assess the effects of water conservation. 2. Evaluate projected compliance with acute toxicity due to ammonia by determining if HWRP’s final effluent will continue to meet the acute toxicity Water Quality Objective in the California Ocean Plan2 . 3. Assess operational alternatives (e.g. treatment optimization, additional treatment, additional dilution credits) to address projected compliance with acute toxicity and ammonia water quality objectives.
